LOOK FOR wnmow Mommas.

Application illed larch 2a, 1920. Serial 170.96318.

The invention relates tolocks and refers more particularl to looks foruse in window regulators to ho d the windowsin their various positionsof adjustment. One of the objects of the invention is to provide a lockwhich is so constructed that it may; be cheaply manufactured. Anotherob'ect is to provide a unitary structure inclu ing the lock and drivingand driven members to facilitate mounting.

With'these as well as other objects in view, the invention resides inthe novel features of construction and combinations and arrangements ofparts as more fully hereinafter. set forth.

In the drawings I I Fi ure 1 is an interior side elevation of a ve icledoor, partly broken away, andshowing a window having a lock embodying myinvention;

Figure 2 is an enlarged vertical section through the lock;

Figures 3 and 4 are cross sections, respectively, on the lines 3-3 and44 of Figure 2;

Figure 5 is a plan view of a portion of the lock.

As illustrated in Figure l, 1 is a vehicle door having an opcnin initsupper portion and a chamber in its Towerportmn for receivingthewindow 2 when lowered from a position closing the opening. 3 1s awindow regulator for raising andlowermg the window and comprising thepivotal lifter arm 4, the crank 5 and suitable mechanism between thecrank and the lifter arm for swinging the latter upon rotation of theformer. This mechanism includes the rack 6, which is pivotally connectedto the lifter arm, and the pinion 7 which meshes with'the rack and isadapted to be driven from the crank 5.

The crank 5 is secured to the drive shaft 8 as by means of the pin 9extending transversely through the hub of the crank and the drive shaft.This pin is secured from accidentaldisengagement by means of theescutcheon 10, which normally extends over the ends of the pin and isieldably heldin this position by the'upho stery ll-located upon theinner side of the door framefand in the present instance the lock board'12. The drlve shaft 8 is polygonal-shaped and is mill stock. The pinion7 is preferably a stamping and is firmly secured between the washer 13and the annular flange 14 of the bearing member 15, both the washer andbearing member being also formed preferably ot' stampings. In thepresent instance the ends of the teethof the pinion 7 extend laterallybeyond the sides of this pinion and into corresponding recesses in theadJacent faces of the washer and bearing member so that the washer,pinion and hearing member'rotate as a unit. The ends of the pinion teethIna be made to extend beyond the sides of t e pinion by a coiningoperation.

The pinion 7 is in, axial alignment with the drive shaft 8 and is driventherefrom by -means of suitable irreversible drive mechanism locatedtherebetween. This drive mechanism includes the hollow hub member 16,preferably formed of a stamping, which has the annular flange 17 rigidlysecured to the outer end of the drive shaft and is provided with theopening '18 intermediate the ends of its cylindrical flange and the slot19 of less width than the opening and leading from the openinglongitudinally of the cylindrical flange to its outer end. 20 is aresilient coiled wire or coil spring surrounding the cylindrical flangeof the hub member and having the inturned ends 21 and 22whichextend intothe opening 18. 23 is a sleeve preferably formed of a stamping extendingthrough and fixedly secured in the lock, board 12 and surrounding thecoiled wire 20 and adapted to be engaged by the convolutions of thesamewhen expanded.

24 is a bearing memberpreferably formed of a stamping surrounding theinner end of the hub member 16 and having an axial portion 25 fittingupon the drive shaft 8 and a radial flange 26 located between thecylindrical flange of the hub member and the sleeve. This radial flangeand the cylindrical flange 27 of the hub member 16 at the opposite endof the wire provide the space between the hub inember and the sleevefor'receiving the wire. 28 is a key member also preferably formed of astamplng and having a projection 28 which is adapted to pass through theslot 19 and lie within the opening 18 of the cylindrical flange of thehub member 16, at which time it is located between the-inturned ends 21and 22 of the wire. This key member has at its inner end thestub shaft29 and at its outer end the rivet: 3.05 the stub shaft ex di g axiallyinto and being journaled in the outer end of the drive shaft 8 and therivet 30 extending axially through the pinion 7 and the.

washer 13 and having at. its outer end the head 31 which cooperates withthe shoulders 32 upon the key member to lirmly secure the washer 13,pinion 7 and bearing mem ber 15 together.

Tohold the parts in operative relation and. to form a unit therebyfacilitating mounting, the sleeve 23 has at its outer end, the inturnedflange 33 which abuts the outer face of the bearing member .15 and nearits inner end the iii-rolled head 34 which is engageable with the radialflange 26 of the bearing member 24, whereby the, bearing members areheld from movement away from each other and consequently the wire, hubmember, key member and associated parts are held in operative relation.The sleeve 23 is also provided near its outer end with the outwardlyextending radial flange 35 which is preferably formed by crimping andwhich is adapted to abut the outer face of the lock board 12. The innerend of the sleeve is provided with the outwardly extending turned-overflange 36 which rests against the washer 37 at the inner side of thelock board, this washer being one of a number of washers of differentthickness and selected to compensate for various thicknesses of the lockboards.

The radial flange 17 of the hub member 16 is fixedly secured to thedrive shaft by reducing the outer end of the drive shaft and sci-ratingthis reduced portion and then forcing the same through the opening inthe radial flange. to form corresponding serrations therein. The outerend of the drive shaft is then turned over upon the radial flange tohold the latter from longitudinal displacement.

It will be seen that rotation of the crank 5 rotates the hub member 16through the drive shaft 8 and one of the edges of the cylindrical flangeof this hub member formed by the opening 18 engages one of the inturnedends of the coiled wire to contract the latter and move its convolutionsinward- 1y away from. the sleeve 23. The inturned end is brougbtintoeTngagen'ient with the projection 28 upon the key men'ibcr 28 and thisrotates this key member and with. it the pinion 7. The pinion being inmesh with the rack will therebyswingthe lifter arm. This operation holdstrue re ardless of the direction of rotation of thecriuik. I'Iowever,with the power removed from the crank and power applied to the pinion Tto rotate the same, this pinion will through the key member '28 and oneof the inturned ends of the coiled wire expand the coiled wire to firmlyengage the sleeve to thereby prevent rotation of the pinion.

From the above description it will be read ily seen that I have provideda lock which is so arranged and constructed that its parts may be formedof stampings or mill stock thereby reducing the cost of manufacture. Itwill also be seen that I have provided a unitary construction includingthe irreversible drive mechanism or look and the drive and drivenmembers.
